    The April 2010 Deepwater Horizon (DWH) oil spill in the Gulf of Mexico resulted in the largest offshore oil spill in U.S. history. The Department of the Interior is playing a major role in many restoration efforts. Two of our largest endeavors are the Deepwater Horizon Natural Resource Damage Assessment (DWH NRDA) and RESTORE Act implementation.
